[one-users] Using CloudInit for contextualization

Thu Feb 6 02:24:06 PST 2014

I've been trying the image and I could not make the user data work.
Cloud-init is able to get networking options and configures the
network but it doesn't restart it so the changes make any effect. It
is also able to get the user data and writes it to the user data file
used later for configuration but it does nothing with it. It could be
a problem with the cloud-init configuration in that machine.

I'll do more debugging as soon as I get some time.
